| Research Abstract |
The objective of this research was to develop a system of simple RPRV (Remotely-Piloted Research Vehicle) flight experiments to study the unsteady aerodynamic characteristics of airplanes.
For this purpose, following hardware developments have been made :
A. Design and manufacture of a generic, testbed vehicle.
B. Development of airdata sensors that can be used with low dynamic pressure.
C. Development of the on-board data acquisition system, the downlink system, and the ground control system.
D. Development of simple optical trackers.
Also, following software have been developed :
A. A computer language for controlling the progress of the flight experiment, called the Menu Control Language.
B. Analysis of flight path and attitude using the tracker data.
C. Conversion, correction, and nondimensionalization of the flight data
D. FPR (Flight-Path Reconstruction) analysis.
E. Identification of models for aerodynamic forces and moments by a direct method.
It has been shown that the study of unsteady aerodynamic characteristics using simple RPRVs is quite practical. Moreover, flight tests of a prototype vehicle with slender delta-wings showed that these vehicle can be flown as a powerless RPRV when combined with a simple roll-damper.
